Well, except that I was trying to say that these options,
including HZxxFONT, are obsolete, and chinese .bdf files
should be used instead. There are all sorts of strange,
antiquated behaviours with these older font subdrivers.

I'm not sure ;-) I don't think either supports unicode input format,
though.
These were contributed very very early before unicode support,
and are builtin fonts only.

No, these aren't scalable. Any freetype asian font would be though.
Only one size can be compiled in at a time. Suggest you switch
to .pcf, .fnt, or .ttf format.

The alignment is probably screwed up for these older fonts.
They do have an ASCII portion however.
